Early production EBMM Axis questions

Are there any differences in the earlier guitars that could impact the value (up or down) compared to the newer production models?

I’m going to be listing it for sale and trying to see what a fair price to ask is? I’ve seen prices all over the place for the ones listed on Reverb.

Mine has a great flamed maple top (trans gold I think is what the color is called) and is in mint condition.
